Application and Oetobor so, 1907. florid No. 899,866.

To all whom it may concern:

Be it known that we, IIIRAM M. HILL and CHARLES O. FARRING'ION, citizensof the United States, residing, respectively, at Dallas and Chicago, inthe counties of, respectively, Dallas and Cook, States of Texas andIllinois, have invented a new and useful Syringe. of which the followingis a specitication.

This invention relates to vaginal syringes and has for its object toprovide an improve ment in vaginal syringes, as hereinafter set forthand claimed.

In the accompanying drawings, forming a part of this specification, andin which like characters of reference indicate corresponding parts,Figure 1 is a view in perspective of a syringe constructed in accordancewlth the present invention. Fig. 2 is a vertical longitudinal sectionalview through the shield. Fig. 3 is a collective detail View of certainattachments that may be employed in connection with the instrument.

Referring to the drawings, 1 designates the bag (ii-reservoir of afountain syringe, with which is connected one end of a length ofordinary rubber tubing 2, the other end of which is secured to oneterminal of the pressure bulb 3, such as in common use. \Vith the otherterminal of the pressure bulb is connected a union at to which isattached a longitudinally curved infiuent or feed tube 5 carrying at itsouter end an approximatel oliveshaped nozzle 6 which is provided wit 1any desired number of perforations 7 arranged in any preferred manner.This nozzle 6 is detachably connected with the tube 5 in the usualmanner. The infiuent tube carries. adjacent to the union at, a pair ofrigid linger holds 8 that are provided to assist in proper nnuiipulationof the instrument in the treatment of various complaints.

h'lountcd upon the influent tube is a dished shield t). that ispreferably, when viewed from its front side, elliptical in contour, andis provided with rearwardly curved or curled edges 10. Projecting fromthe rear wall of the shield, and preferably at its central point, is anexternally threaded boss 11 that is designed to receive an internallythreaded cap gland 12 through which extends the tube 5. As clearly shownin Fig. 2, the bore of the boss 11 is of somewhat greater diameter thanthe tube 5 in order to accommodate a resilient gasket 13 which is longerthan the boss and is adapted to be compressed by the cap gland andthereby temporarily secure the shield at any desired point on the tube 5according to the requirement of the case.

The shield may be made of any suitable material, preferably one that isaseptic, and is provided, at its rear side below the boss,

with an obliquely disposed eliluent tube 14.

to which is adapted to be connected a drainage pipe, (not shown) thatwill extend to a suitable receptacle. In order to retain the drainagepipe upon the etliuent tube the latter is provided with a bulbous head15, as clearly shown in Fig. 2.

As will be seen by reference to Fig. 1, the rear end of the tube 5 orthat carrying the finger holds is internally threaded to receive theexternally threaded terminal 16 of the union 4-, the object of thisarrangement being to permit ready detachn'ient of the pressure bulb fromthe tube 5 when a medicament is to be applied. Under such conditions, asupplemental pressure bulb 17 will be employed which will contain themedicament and which is provided wit-h a threaded extension 18 to engagewith the rear end of the influent. tube.

To extend the range of usefulness of the device as for the treatmentofear or nasal diseases or for infants uses, a set of nozzles, shown inFig. 3, is provided, and designated respectively 19, 20 and 21. Each ofthese nozzles has its rear end provided with a threaded extension 22that is adapted to engage a cup-shaped guard 23, the latter beingdesigned to screw upon the threaded extension 18 of the bulb 17. As willbe obvious, the series of nozzles 19, 20 and 21 are interchangeable, asis also the small nozzle 24, so that any character of disease may bereadily treated.

The essential feature of the present invention is the particular meansfor adjusting the shield 9 upon the tube 5, it being seen by Fig. 1,that it can be shift-ed throughout the entire length of the said tube,whereby to adapt the latter to meet any contingency that might arise inthe use of the instrument. Moreover, the peculiar shape of the shield isof importance inasmuch as it will ositively preclude escape of liquidsor medicaments, which latter will be carried 01f through the pipeconnected with the eflluent tube 14:.

Having thus described the invention what is claimed is In a vaginalsyringe, the combination with an influent tube, of a concave-convexshield 10 with an integral nipple for the reception of a discharge tube,there being an exteriorly threaded integral boss projecting from theconvex side of the shield and through which the tube extends, a gaskethoused in the boss,

and a cap gland carried by the boss and serv- 15 mg to compress thegasket and hold the shield in place upon the tube.

In testimony that we claim the foregoing as our own, we have heretoafiixed our signatures in the prescence of two witnesses.
